Climate data generally falls into two categories: historical data and data from recent and current observations. While most people understand the importance of current and recent climate data, fewer appreciate the equal importance of historical climate data.

Historical climate data records help us develop climate models, satellite-based instruments and seasonal forecasts, as well as provide foundational data for adaptation studies at local, national and regional scales. For example: Climate models are mathematical representations of the interactions between the atmosphere, oceans, land surface, ice and the sun. Once a climate model is developed, it has to be tested to find out if it works. And since we can’t wait for 30 years to see if a model is any good or not, the models have to … Read more
